hello, today i got some strange error in my Dell Latitude D630 laptop . when i do restart to my laptop , i get this error: "No bootable devices--strike F1 to retry boot, F2 for setup utility press F5 to run onboard diagnostics" no matter what i do i cant pass this screen just by press f1. now i have install windows 7 home edition and i notice that when i place the setup disk in my DVD drive , windows is starting. once i get to windows , its look like everything is ok, my hdd is recognized with no issues. i did a reinstall windows but this error keep on going. what it could be ?
